Open Hardware/Modding: Open Source Waterwheel, Lichee Pi, and Raspberry Pi

• Open Source Waterwheel

  Here in the West, power going out is an unusual event. But in more remote regions like the Himalayas, reliable electricity isn’t a given. A group of local craftspeople, researchers, and operators in Nepal have worked together to devise a modular waterwheel system.

• Lichee Pi 4A RISC-V Desktop Gets Unboxed, Offers Strong Linux Performance

  Christopher Barnatt with ExplainingComputers gives us an up close look at the new Lichee Pi 4A RISC-V computer.

• Soundproofing my studio: what's in a wall?

  And every sound has it's own characteristics. Like the train tracks that run outside my office: they transmit sound through the earth, meaning if I wanted to soundproof my room from that, I'd need to spend thousands of dollars isolating the floor entirely.

• MediaPipe for Raspberry Pi released – No-code/low-code on-device machine learning solutions

  Google has just released MediaPipe Solutions for no-code/low-code on-device machine learning for the Raspberry Pi (and an iOS SDK) following the official release in May for Android, web, and Python, but it’s been years in the making as we first wrote about the MediaPipe project back in December 2019. The Raspberry Pi port is an update to the Python SDK and supports audio classification, face landmark detection, object detection, and various natural language processing tasks. MediaPipe Solutions consists of three components: MediaPipe Tasks (low-code) to create and deploy custom end-to-end ML solution pipelines using cross-platform APIs and libraries MediaPipe Model Maker (low-code) to create custom ML models MediaPipe Studio (no-code) webpage to create, evaluate, debug, benchmark, prototype, and deploy production-level solutions.
